PROBLEM TO BE SOLVED: To provide an information transfer method/system for improving the availability of a communication line. SOLUTION: A client machine 402 receives and changes a file which a server machine 401 holds and a difference detection part 402h detects a difference between the changed file and the original file before a change. A differential signal showing the difference between the changed file and the original file is transmitted to the server machine 401. The server machine 401 receives the difference signal transmitted from the client machine 402, changes the file which the server machine 401 holds by using the differential signal and executes the change which the client machine 402 executes. |
